Description

Technical Field

[0001] The present invention relates to the technical field of container ship cabin layout design, and in particular to a container ship cargo hold capable of loading and unloading cargo under a superstructure. Background Art

[0002] In recent years, the container shipping industry has ushered in a structural prosperity, the market sentiment has continued to rise, the volume and freight rates have risen, but the capacity is in short supply. Faced with the lucrative profit returns, major global shipping companies are ordering new ships in large quantities, which has led to new shipbuilding orders hitting record highs. In addition, in order to pursue economies of scale and increase the volume of transportation, the size of container ships is also constantly increasing. How to further increase the container ship's loading capacity and increase economic efficiency has become a problem worthy of attention.

[0003] Starting from the 10,000-TEU container ships, the "double island" design is generally adopted, that is, the engine room and the engine room shed are located at the stern as the rear island, while the superstructure including the cockpit and living cabins are located in the middle and front part of the ship as the front island. This design takes into account the impact of loading containers on the driver's line of sight. Compared with the "single island" design where the superstructure is located at the stern, it is more conducive to increasing the loading capacity. However, due to the obstruction of the superstructure, the hull space below it cannot be used to load containers, resulting in a waste of space. Most of the existing design schemes arrange fuel tanks or LNG tanks under the superstructure to maximize the utilization rate, but it is not the best layout scheme.

[0004] In summary, the current “double-island” layout of ultra-large container ships has the problem of insufficient utilization of the cargo hold space under the superstructure. Summary of the invention

[0005] In view of the above-mentioned problems existing in the prior art, the present invention aims to provide a container ship cargo hold capable of loading and unloading cargo under the superstructure, which can realize loading containers in the hull space under the superstructure to improve the utilization rate of the hull space, increase the loading capacity of the container ship, and make the ship type more economical.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention provides a container ship cargo hold capable of loading and unloading cargo under a superstructure, comprising a cargo hold, a watertight transverse bulkhead, a supporting transverse bulkhead, a main deck, a superstructure, a container trolley and a container transfer device; the watertight transverse bulkheads are arranged at the front and rear of the cargo hold, the supporting transverse bulkhead is arranged in the middle, and containers can be loaded inside; the front half of the cargo hold is in the form of a large opening, the rear half is arranged with the main deck, and the superstructure is arranged on the main deck;

[0007] The container trolley is arranged at the bottom of the cargo hold, and the container transfer device is arranged under the main deck. The container trolley and the container transfer device cooperate with each other to realize loading the container into the hull space under the superstructure.

[0008] Preferably, the surface of the container trolley is in the form of a rectangular flat plate, and a plurality of wheels are provided at the bottom, so that the container trolley can move forward and backward at the bottom of the cargo hold.

[0009] Preferably, the container trolleys are symmetrically arranged at the bottom of left and right sides of the cargo hold.

[0010] Preferably, limit baffles are symmetrically arranged on both sides of the middle position of the container trolley.

[0011] Preferably, stack cones are symmetrically arranged at the front and rear positions of the container trolley.

[0012] Preferably, the container transfer device comprises a transverse track, a longitudinal track and a container crane, the longitudinal track can move left and right on the transverse track, and the container crane can move forward and backward on the longitudinal track.

[0013] Preferably, the main deck is in the form of a plate frame structure, which includes a plurality of longitudinal girders and a plurality of transverse beams, and the transverse rails are connected to the longitudinal girders and the transverse beams through a plurality of toggle plates.

[0014] Preferably, the container includes but is not limited to a 20-foot standard container and a 40-foot standard container.

[0015] Preferably, the front half of the cargo hold is provided with a hatch cover.

[0016] Preferably, a fuel tank is arranged in the middle of the watertight transverse bulkhead.

[0017] The positive effects of the above technical solution are:

[0018] 1. Through the coordinated use of container trolleys and container transfer devices, the hull space below the superstructure can also be used to load containers, thereby improving the utilization rate of the hull space below the superstructure and increasing the loading capacity of the container ship;

[0019] 2. The main deck below the superstructure adopts a plate frame structure, which can reduce the space occupied in the height direction of the cargo hold;

[0020] 3. The transverse bulkhead in the middle of the cargo hold adopts a supporting transverse bulkhead. Compared with the scheme of arranging the fuel tank under the superstructure and adopting a watertight transverse bulkhead, the structure is lighter and helps to save construction costs;

[0021] 4. Fuel tanks can be set up in the front and rear watertight transverse bulkheads as an alternative to the layout of fuel tanks. This solution does not occupy other tank spaces, makes full use of local space, and has a more optimized layout. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the attached Figure 1 To Attachment Fig.17 The technical solution provided by the present invention is described in detail, but the following content is not intended to limit the present invention.

[0041] Figure 1 to Figure 6 The structural diagram of an embodiment of a container ship cargo hold capable of loading and unloading cargo under a superstructure of the present invention is shown (only the port side, symmetrical on both sides), including a cargo hold 1, a watertight transverse bulkhead 2, a supporting transverse bulkhead 3, a main deck 4, a superstructure 5, a container trolley 6 and a container transfer device.

[0042] The present invention can realize loading containers 12 in the hull space below the superstructure 5 by using the container trolley 6 and the container transfer device, which is beneficial to improving the utilization rate of the hull space, increasing the loading capacity of the container 12 ship, and making the ship type more economical. Among them, the container 12 described in the present invention includes but is not limited to a 20-foot standard container 12 and a 40-foot standard container 12.

[0043] Specifically, two watertight transverse bulkheads 2 are respectively arranged at the front and rear of the cargo hold 1, and a supporting transverse bulkhead 3 is arranged in the middle, and containers 12 can be loaded inside. The front half of the cargo hold 1 is in the form of a large opening, and the rear half is provided with a main deck 4, and a superstructure 5 is arranged on the main deck 4. Container trolleys 6 are symmetrically arranged at the bottom of the left and right sides of the cargo hold 1, and a container transfer device is arranged under the main deck 4.

[0044] By using the container trolley 6 and the container transfer device in coordination, the hull space below the superstructure 5 can also be loaded with containers 12, thereby improving the utilization rate of the hull space below the superstructure 5 and increasing the loading capacity of the container 12 ship.

[0045] In addition, the transverse bulkhead in the middle of the cargo hold 1 adopts a supporting transverse bulkhead 3, which is lighter in structure weight and helps to save construction cost. As a preferred embodiment, a hatch cover 10 can be set in the front half of the cargo hold 1, which is helpful to increase the loading capacity for large containers 12.

[0046] As a preferred embodiment, a fuel tank 11 may be arranged in the middle of the watertight transverse bulkhead 2 as an alternative to the conventional arrangement of the fuel tank 11. This arrangement does not occupy other tank spaces, makes full use of the local space, and has a more optimized arrangement.

[0047] Figure 7 The structural schematic diagram of the main deck 4 of a preferred embodiment of the present invention is shown (only the port side, symmetrical). The main deck 4 is a plate frame structure, and its main components include a plurality of longitudinal girders 41 and a plurality of transverse beams 42, forming a cross beam system. The container transfer device is installed under the main deck 4 and connected to the transverse track 7 through the brackets 13 on the longitudinal girders 41 and the transverse beams 42.

[0048] The structural form of the main deck 4 not only ensures that it has sufficient strength to support the superstructure 5 and the container transfer equipment below, but also reduces the space occupied in the height direction of the cargo hold 1, so as to load as many containers 12 as possible.

[0049] Figure 8 The schematic diagram of the structure of a container trolley 6 of a preferred embodiment of the present invention is shown. The surface of the container trolley 6 is a rectangular flat plate, which can load two 20-foot or one 40-foot containers 12, and the front and back and middle positions of the flat plate are respectively symmetrically provided with stacking cones 62 and limit baffles 63, which are convenient for fixing the containers 12 during loading and unloading. A plurality of wheels 61 are provided at the bottom thereof, so that the trolley can move forward and backward at the bottom of the cargo hold 1, so as to realize the displacement of the containers 12 along the length direction of the ship.

[0050] Fig. 9 , 10 The schematic diagram of the structure of a container transfer device of a preferred embodiment of the present invention is shown. The container transfer device is composed of a transverse track 7, a longitudinal track 8 and a container crane 9. The longitudinal track 8 can move left and right on the transverse track 7. The container crane 9 can lift a 20-foot or 40-foot container 12 and move forward and backward on the longitudinal track 8. The transfer device can realize the transfer of the container 12 between the container trolley 6 and the cargo hold 1 below the superstructure 5.

[0051] Figures 11 to 17A schematic diagram showing the operation of loading and unloading cargo in the cargo hold 1 of a container 12 according to a preferred embodiment of the present invention is shown ( Fig.12 and Fig.14 Only the port side, symmetrical). The following is a detailed description using the loading process as an example.

[0052] The empty container ship 12 is docked at the dock, and the hatch cover 10 is first lifted away by the dock crane 14 on the shore, and then the container 12 is lifted to the front half of the cargo hold 1. The container trolley 6 moves to the middle of the front half of the cargo hold 1, and the container 12 is lifted onto the container trolley 6. One or more containers 12 can be loaded, but the maximum loading quantity cannot exceed the height that the container trolley 6 can smoothly pass through the supporting transverse bulkhead 3.

[0053] After loading, the container trolley 6 moves along the length of the ship to the rear half of the cargo hold 1, that is, under the superstructure 5, and then uses the container transfer device under the main deck 4 to lift the containers 12 on the container trolley 6 to other positions in the cargo hold 1 one by one. When unloading is completed, the container trolley 6 returns to the front half of the cargo hold 1, and the dock crane 14 continues the loading operation. While the container trolley 6 is waiting for unloading in the rear half of the cargo hold 1, the front half of the cargo hold 1 can be loaded synchronously.

[0054] Finally, when the maximum loading capacity is reached under the superstructure 5 except for the container trolley 6, the container trolley 6 is loaded to the maximum height in the front half of the cargo hold 1, and then returns to the bottom of the superstructure 5 and parks. The dock crane 14 completes the loading of the front half of the cargo hold 1 and then hoists it back to the hatch cover 10, and then continues to load the quota of containers 12 on the hatch cover 10. At this point, the entire loading task of the cargo hold 1 is completed.

[0055] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
